从datgridview和数据库访问中删除行 [ ^ ]

我希望这能帮到你！

  int  index = GridView1.SelectedIndex; 
 gv.DeleteRow（index）;  //  使用gridview实例的deleterow方法（gv是你的gridview实例）  

从数据表中删除

 DataTable dt =  new  DataTable（）;  //  您的数据表实例 
 //   index = dt.Rows.IndexOf（dr）; //获取指定行的索引 
 dt.Rows [index] .Delete（）;  //  删除行 

更多方法：

 dt.Rows.RemoveAt（index ）;  //  如果您知道行索引 
 //   dt.Rows.Remove（dr）; //如果你有指定行的实例 

，请使用它>
